Hi, I'm setting up OC 3.0.2.0 and one thing is giving me issues - the newsletter.

Firstly, it seems I can access it from two areas - Marketing -> Mail, and Ext. -> Ext. -> Modules -> OC Newsletter. Frankly, I have no idea if that's a byproduct of using a 3rd party template (Handart by Plaza), or if it's supposed to be that way, or.. what. But in any case, the first gives me an "error_mail" when I attempt to send, the second gives me no error (nor confirmation of anything happening) but nothing is sent. I get confirmation of orders, so it's presumably not an issue with my mail setup.
